- Mass of the car (m) = 2000 Kg
- Initial velocity (u) = 15 m/s
- Force (F) = 10000 N
- Time (t) = 3 s
- Let the acceleration be a.
- By using the formula, F = ma, we get,
- 10000 N = 2000 Kg × a
- or, a = 10000 N ÷ 2000 Kg
- or, a = 5 m/s^2
- Let the final velocity be v.
- By using the formula, v = u + at, we get,
- v = 15 m/s + 5 m/s^2 × 3 s
- or, v = 15 m/s + 15 m/s
- or, v = 30 m/s

Hope you could get an idea from here.
Doubt clarification - use comment section.
it would be at either A or B.
Answer:
605 km
Explanation:
Hello
the same units of measure should be used, then
Step 1
convert 42 m/s ⇒ km/h
1 km =1000 m
1 h = 36000 sec


Step 2
find kilometers traveled after 4 hours

V,velocity
s, distance traveled
t. time
now, isolating s

and replacing

S=604.8 Km
Have a great day
Answer:
The Mitochondria generates most of the chemical energy needed to power the cell's biochemical reactions.
Explanation:
I studied the body organisms 2 years ago.
Your answer would be motion because u need force to stop motion or anything at that matter
